Candidate cause (the documents say what to do)
Starter keeps cranking after the key is released (PCM-controlled automatic crank, normal)
On these vehicles the PCM controls the starter relay, with input from the key switch; after 0.4 seconds of cranking a timer is activated in the PCM.
Once the timer is active, the PCM continues to crank the starter even though the key is released, until the engine starts or a no-start time limit is reached.
What to do
No technical document states a check or a repair.
Caution: This is a normal condition and no repairs should be attempted for it.
In the records
No record states work done for this cause.
